It is an object of this invention to construct a golf shaft which atmost costs but slightly more than the ordinary steel shafting and whichhas the lasting qualities of steel and the good playing qualities ofwoodin other words a steel shaft with a wood feel.

A still further object of this" invention is to construct a shaft for agolf club which is characterized by a hollow tubular metal steel" shaftof usual designwith a core or sponge rubber.

As a still further object of this invention it is proposed to use thehollow shaft as the moldfor the sponge rubber core. The core thereby iscemented or held firmly in place without further handling after molding.This method is recommended,although the core can be molded separatelyand later inserted and cemented in the hollow shaft.

A still further object of this invention is to construct the shaft witha double wall and to fill the rubber sponge core in between the doublewall or inside within the inner wall, or at both places.

The invention furthermore proposes the provision of means for changingthe resiliency and shock absorbing qualities ofthe rubber core.

A still further object of the invention is the construction of a shaftfor golf clubs and the like which is of simple durable construction,dependable in use and efficient in action, and which can be manufacturedand sold ata reasonable cost.

For further comprehension of the invention;

and of the objects and advantages thereof, refer,-

ence will be had to the following description and accompanying drawings,and .to the appended claims in which the various novel features of theinvention are more particularly set forth.

In the accompanying drawings forming a material part of thisdisclosure:- I

Fig. 10 is a view similar to Fig. 9, but showing the strip within therubber core turned at a 90 angle so as to change the resiliency of thecore.

A golf club constructed according to this invention comprises a hollowmetal shaft 10 or tubing covered at the top with a grip 11 ora leatherwrapping. At thebottom an iron head -12 is shown attached upon themetalshaft or tubing by a rivet 13. When thus arranged the metaliron head isin intimatecontact with the metal shaft or tubing. Vibrations which tendto be set up in the shaft when a golf ball is struck will be directlycommunicated from the iron head to. the shaft in that they are inintimatecontact. A rubber 14 is disposed within the view taken on theline '9- -9 V absorb the vibrations.

If one so desires, the iron head may be insulated from the shaft bysuitable vibration absorbing material engaged around the bottom end ofthe shaft and disposed between the parts. A- cap or a plug 15 is engagedwithin .the free-end of the tubing so as'to close it. In Fig. 3 thesponge rubber core is very clearly shown within I the wall of thetubing. X

This invention eliminates the objectionable 'shock or vibrationtransmitting character of ordinary steePgolf shafts. The golf club shaftaccording to this invention ha's'the desirable qualities of steel, beingfundamentally of similar construction, and hasin addition the sweet feelof wood shafting. The new golf club shaft eliminates objectionable shockor vibration and in addition does the following: 1

l. Strengthens the shaft against breaking.

2. Makes the whipping point further down on the shaft than the ordinarysteel shaft-which is considered a desirable playing quality.

3. Gives the entire club a better or improved dynamic balance orswinging weight. This dynamic balance is effected by improved torsionalqualities, specific gravity, etc., due to its inherent H nature. 105

The hollow shaft can be used as amold for the sponge rubber core, thecore thereby being cemented or held firmlyin place without further Whilethis method of the core may be made separately and later inordinarycomfort and satisfaction due to freesorted in the hollow shaft.
